Research Project: MANAGEMENT OF FUSARIUM HEAD BLIGHT OF WHEAT IN MARYLAND Project Number: 0500-00053-002-85
Project Type: Grant

Start Date: Mar 31, 2009
End Date: Mar 30, 2014

Objective:
Project Title 1: Management of Fusarium Head Blight of Wheat in Maryland – Uniform Fungicide Trial Component. This project will examine the effectiveness of an agreed standard set of fungicides on suppression of Fusarium head blight disease, and on accumulation of the disease-associated mycotoxin, deoxynivalenol (DON), in various environments and wheat classes. Project Title 2: Management of Fusarium Head Blight of Wheat in Maryland – Uniform Integrated Management Trial Component. Trials will be conducted in multiple states and wheat classes to test the efficacy of combining tactic into an integrated management program for Fusarium head blight of wheat.

Approach:
Project Title 1: The Maryland trials are being conducted in the soft red winter wheat (SRRW) production region of the Eastern/mid-Atlantic production region. The Maryland contribution to the uniform fungicide trial component of the FHB management coordinated project includes the examination of several additional combinations and products beyond the standard set and will also examine the effect of delayed applications of several best performing products on DON accumulation. All commercial applications of fungicides are unlikely to be applied at the initiation of flowering and therefore it is important to determine the effective application window. Project Title 2: The Maryland trial will be conducted in the soft red winter wheat (SRRW) production region of the Eastern/mid-Atlantic production region. Six adapted SRWW cultivars representing the range of available resistance to the disease will be grown with and without the best available fungicide treatment to determine if the combination of individually moderately effective tactics produces a more effective management of the disease. A total of four trials will be conducted in 2 location following 2 different rotation schemes to provide a range of disease risk situations representative of production practices in the region.
